SECURING MEANS FOR LOCK HOUSINGS.

Application filed June '7, 1953. Serial m. 643,961.

To all whom it may concern: 7

Be it knownthat I, FRANK ELLIsoN Bns'r, a citizen of the United States, residing at Seattle, in the county of King and State of l Vashington, have invented a new and useful Securing Means for Lock Housings. of which the followingis a specification.

My invention relates to improvements in means for securing locks and lock housings to doors or to other members on which they are installed and theobject of myinvention is to simplify, cheap en and increasethe eflicienc'y of devices of this nature.

Another object is to provide a lock securing means that isabsolutely inaccessible to any persons except those having proper keys to, the lock.

Other objects are to provide lock securing means that is especially well adapted for use in connection with locks on the doors of automobiles of the enclosed car type or for use in connection withlocks of the form commonly known as night latches.

A more specific object is to provide lock securing means of this nature in wliich a 1001; housing .is embedded in a member to which it is to be anchored and is secured thereto by a screw that is inserted from the inside of the lock housing, projects through the end of said housing and screws into any member to which the lock housing is to be secured, the lock housing being an ran-gedto have a lock core removably locked therein; said removable lock core making it possible to use lock housing securing means of this nature.

Other and more specific objects will be apparent. from the following description taken in connection with the-accompanying drawings.

In the drawings Figure 1 is a view in end elevation of a lock constructed in accordance with this invention a fragment only of the door or member in which said lock is in-- stalled being shown: I

Fig. 5 is a fragmentary view'i'n elevation showing an adaptation of this loc' k seciiring means to a night latch' tyipe of. lock, the inner'sideof the night latch. being shown together with a jtjra-gment of the door and the core case ofthe lock with the -core 1e moved. I I I Fig. is a setional view taken on broken line '6 6 of 5 showing then-ight latch portion only ofthe device. in Fig. 7 is a sectional view on line-7+7 of Fig. 5. V v Q v 8 is a detached perspective-of the base plate of the night latch. u i Fig. is a fragmentary detached perspective of the housing of the night latch.

- Fig. 10 is a fr ment'ary sectional ,view illustrating a modified form of night latch housing. 7 Like reference numerals designate like parts throughout-the several v iewls.

Referring, to Figs. 1 to 41 inclusive, the numeral 5 designates a lock housing pm vided with an internal recess 6 of figure 8 cross sectional shape 'tttlfiptfid for the reception of a lockcore 7 of the pin tumbler type which is arranged to be locked yv' it'hin the housing by-a movable gate 7, Fig. '4 which engages behind a shoulder 5 ind-icated 'by dotted lines Fig, 3, the pin tumbler lock being of the double shear linetyp'e described in my .pr-ior Patent No. 1, 384e,022 issued July 5, 1921, in which one shear line of the lock performs the usual locking function' while the other shear line controls the movement of the gate 7 for unlocking and removing the core from the housing thus making it possible for a person having a proper: key to remove the core and gain access tothe recess 6 within the housing. Thehousing 5 is disposed within asuitable recess in a lock receiving member 8, which may be a door. or door casing, and is secured to said member 8 by a screw 9 "which projects through the bottom of the lock housing 5 and is screwed into the member 8 as shown .in Fig. 2-.

The provision of a removable core 7 in the lock housin makes possible the use or" the screw 9 in the botto of the lock hons- ,ing which forms an exceptionally simple and efficient means for securing the lock housing to the member 8. Access to the screw 9 may be had oer when the lock core 7 is removedaiid said ock core maybe removed only by authorized persons having the proper key. 1 In autcmebile bcd'ies of the ti pc to which this lock is particularly adapt d the member 8 is ordinarily the frame of a door and said member 8 is provided with an external covering 10 of sheet metal with which a flange 11 0n the outer end of the lock housing engages.

The lock core 7 is provided with a key plug 12, arranged to be rotated by the insertion of a proper key in a key slot 18, said key plug 12 having a disc 14 secured to the inner end thereof that is provided with two outwardly protruding pins 15 arranged to project into slots 16, Fig. 3, in a disc 17 on the end of a latch operating bar 18. The latch operating bar '18, which is of standard construction, is connected with suitable latch mechanism also of standard construction. not shown. 7

The latch operating bar 18 may be of square or rectangular cross sectional shape, in which instance it is preferably provided with a circular collar 19 that is rotatable in a suitable opening in the end of the lock housing 5. The inner end of the lock housing 5 is internally recessed to afford working clearance for the disc 17 on the end of the operating bar 18.

The end of the lock housing 5 is preferably flat and fits squarely against the end of the recess in the member 8 in which said lock housing is inserted.

In installing this device it 18 only necessary to place the lock housing 5 in the recess in the member 8, insert the wood screw 9 and then insert the core 7 and lock the same in place. The latch operating bar 18 is preferably readily removable with the housing 5.

The location of the screw 9 is such as to render it inaccessible except by first removing the lock core thereby making the look very difficult to tamper with.

In Figs. 5 to 10, I have shown this i11- vention as applied to a night latch comprising a night latch housing 20 arranged to fit over a base plate 21 that is secured to a door 22. The forward end of the base plate 21 is provided near opposite corners with raised hook-like lugs 23 that are arranged to be engaged by inwardly extending flange portions 24: on the forward end of the lock housing 20 to secure the forward end of the lock housing to the base plate. A flat tongue portion25 is provided on the base plate 21 between the lugs 28 to support a latch bolt, not shown. Any suitable night latch mechanism, not shown, may be used in the night latch. The base plate 21 is secured to the door 22by screws that are inserted through holes 26 and such base plate is provided with a perforation 27 into which the end of a lug 28 that is integral with the housing 20 may protrude.

The lug 28 is provided with an internally threaded recess 29 for the reception of a screw 30 that extends through the bottom of a lock housing 31 having a removable lock core 32 provided with a rotatable disc 33 having pins not shown, corresponding to the pins 15 shown in Fig. 4 that engage within perforations 3a in a disc 35 on the end of a rotatable latch operating bar 36, all of said parts being substantially identical with and functioning in the same manner as those shown and described in connection with Figs. 1 to a.

In installing this device, the door 22 is rec seed on one side for the reception of the core housing 31 and the base plate 21 is secured to the opposite side of said door. The night latch housing 20 is applied by inserting the flanges 24 under the lugs 23 and pressing the night latch housing rearwardly and inwardly until the edges of said housing drop over the edges of the base plate and the lug 28 ent-zrs the perforation 27. The core housing 31 and the night latch housing 20 are then both securely fastened to the door 22 by inserting the screw 30. Access to the screw 30 is prevented by insertion of the core 32 in the core housing 31. The screw 30 is relatively large and strong and forms a substantial lock securing means that is inaccessible except to persons having a proper key. When the night latch housing 20 is removed from the door it will, at the same time be removed from the plate 21 thus affording instant access to the mechanism within said night latch.

Figure 10 shows a modified form of night latch housing 37 in which'the front end of the housing is extended as at 38 so as to lap over the front edge of a door and is provided with spike or barb members 39 arranged to be driven into the edge of the door to secure the front end of such night latch housing to the door. The night latch housing shown in Fig. 10 makes it possible, if desired, to dispense with the base plate, as base plate 21, which is ordinarily provid:;d in connection with this form of night latches, the screw 30 serving to hold the rear portion 'of the housing 37 in the manner hereinbefore explained in connection with Figs. 5 to 9 inclusive.

The foregoing description and accompanying drawings clearly disclose what I now consider to be a preferred embodiment of my invention but it will be understood that changes in the same may be resorted to within the scope of the following claims.
